i IMPROVEMENT IN GRAIN-DRILLS.`

Specification forming part of Letters Patent No. 53,005, dated March 6, 1866.

To all whom it may concern.-

Beit known that I, JOSEPH INGELS, of Milton, in the county of Wayne and State of Indiana, have made new and useful Improvements in Seeding-Machines and I do hereby declare the following to be a full, clear, and exact description of the nature, construction, and operation of the same, reference being had to the accompanying drawings, which are made part of this specification, and in which- Figure 1 is a plan View of my machine. Fig. 2 is a vertical section on thelinewx, Fig. l. Fig. 3 is a side elevation of the hopperhead or end of the box containing the seed. Fig. 4 is a View of two descriptions of feedwheels, of which the one on the left illustrates my improvement. Fig. 5, first, is an elevation, and, second, a section of the wheels, which are interposed between the drivingshaft wheel and the feedshaft wheel. Fig. 6 are views of the various comparative sizes of the said interposed wheels, by selection from which the rate of feed is changed, as will be further described. Fig. 7 is an elevation View from the rear ofthe feed-wheel, and of the concave in which said wheel revolves. Fig. Sis an elevation of the feed-wheel, detached from its shaft and from the concave. Fig. 9 is a plan or top view of the concave detached from its surroundings, with the exception of a portion of the feed-shaft.

The same letters in the different iigures indicate corresponding parts.

My invention consists, trst, in an arrangement for varying the feed, and it is accomplished by the provision of two slots in the hopper-head at dierent radial distances from the driving-shaft, and in either of which may be placed a shifting axis provided with changeable wheels; secondly, in the construction of the lever-bar loops by the revolution of which the hoes are elevated; thirdly,in the construction of the feed-wheel in respect of the shape of its teeth; and, fourthly, in the form given to the lower plate or discharge-orice of the concave in which the feed-wheel rotates.

To enable one skilled in the art to which my invention appertains toconstruct and 4use the same, I will proceed to describe it. I

A is the frame of the drill; B, the tongue; (l G, the wheels; D, the hopper in which the seed is placed 5 E E, the hopper heads or ends,

F, the lid of the hopper; G, thedrag-bar, and H the hoe, of which there is a series, each hoe receivingseed from its appropriate feed-wheel, which rotates below the hopper. 4

. I is a shaft which extends the length of the hopper and carries the series of feed-wheels J, each of which rotates in its appropriate concave, K. The said shaft is driven by gearing from the main driving-shaft L in a manner to be described.

The main driving-shaft L is provided with a geared wheel,which may be called No. 1,? and this meshes with the gear-wheel No. 2, which is on a short axis, Fig. 5, formed by the bolt and sleeve M N, and secured into either of the slots P P. The Wheel No. 3 is secured to the wheel No. 2 by the engagement of the pins, projections, or clutch exhibited in Fig. 5 at m m, so that these two wheels (2 and 3) rotate together, wheel No. 3 meshing into Wheel No. 4, (which I term the clutch-wheel,) and which is on the feed-wheel shaft I, running ,freely thereon, until, by the trigger Q, it is brought into engagement with the corresponding clutch on the head of the shaft I.

The seed, as it falls from the dischargeorilice of the concave, is conducted by channels'R S to the hoe H, and the latter are raised as may be required by the lever T, which rotates the bar U, to which the hoe-chains are attached.

These chains pass over the V-shaped piecesV as the bar U is rotated. This latter action, by the impingement of the plate U upon the lever V', has the effect of unclutchin g the wheel No. 4 and shutting off the feed.

' The wheels shown in Fig. 6 are the changeable wheels, which are made to occupy the positions shown in Figs. 1 and 2, between Vthe wheel on the driving-shaft No. l and the clutch-wheel on the feed-shaft No. 4. This change is made to vary the speed of No. 4, according to the varying necessities of the case, to sow little or much, asiffay be desired.

It will be apparent that if the size of No. 3 is reduced from that shown in situ in Fig, 2 the rate of motion of No. 4 will be reduced in consequence 5 but my invention consists of something more than a singleseries.

There are two slots, P P', in either of which 4the spindle of the changeable wheel is placed. The object of these is toenable a greater number of variations of the feed than is possible with but one slot 'for said axis, for when butV one slot is used, the wheel No. 2, or that next iu series to wheel No. l, the main sha-ft or axle will be a constant size, and the number of changes Will be equal to the number of the wheels which connect wheel No. 2 with the clutch-wheel No. 4.

the other slot. A change in` the third Wheel only requires that the axis, in whichever slot it may be, is rocked back or forth, as the case maybe, so that the teeth ot' the third may mesh into those ot' the clutch-wheel No. 4.

As arranged, the No. 8 and No. 4wheelsare used as second wheels, the lat-ter in the slot nearest the driving-shaft. When No. S is in the upper slot the machine is adapted to sow Wheat, rye, barley, in any desired quantity, regulated by means of the selection for athird wheel from among the others. Using No. 4 second Wheel increasesthe speed and therate of feed, and, in connection with a suitably-selected third wheel, adjusts the rate to sow' the required quantity ot' oats. The quantity of each grain sown is, as has been said, regulated by the wheels, which are calculated to sow'a specic quantity each of agiven grainfor instance, with No. 8 as a second wheel and No. 1 as a third wheel three pecks per acre' of wheat are intended to he sown. With a change of No. 2 in the place of No. l the amount is increased to one bushel, &c. *To4 produce the same result with rye in quantity sown, one size larger of the third wheel will beused than with wheat, as the latter feeds` through a given opening fasterl than rye.

The gearing described is all placedinside of the'hopper-head, and is there protected against dirt, brush, or other things which are lgathered up by and drop from the wheel, as also from other casualties incident to a more exposed or exterior position. This desCripiliOn may suice for this part of my invention.

from the outside toward the centerthat is, `from the cheeks of the concave K toward its center, preventing mashin g of the seed. The door ot' the concave has a V shape, whose point 7a projects in a direction the reverse of those on the feed-wheel. The grain is drawn for- Ward by the teeth of the revolving Wheel and pushed over the edge ot' the floor of the concaye. lt is desired that this action maybe continuous and entirely freed from all intermit` tent character. For this purpose, as the V- shaped teeth and opening cross each other before the grain against any one tooth is all pushed out over the point k ot' the V-shaped bottom, the outer flanges of the next tooth have commenced to push over t-he grain at the receding portions at edges Zot the said hottom or hoor.

Having thus described my invention, what I claini therein as new, and desire to secure by Letters Patent, is-

l. The changeable gearing placed inside ot' the hopper-head.

2. The series (two or more) of slots in the hopper-head or other plate, for the purpose of adjusting the movable axis to suit the change of Wheels.

3. Joiningthe diagonal teeth of the feedwheel inthe middle of the roller.

4. The vfshaped projectionk on the door of the concave,`for the purpose described.

To the above specification ot' my improvement in grain-drills I have signedA myhand this25th day of May, 1865.
